new and useful Improvements in Typewriting Machines, of which the following is a specification. j

This invention relates to improvements in ,typewriting, machines, and more particularly to means for supporting and guiding the type-barsegment in typewritingma chines in which the type-bar segment is shifted relatively to the platen for printing characters of different case. j

The invention hasfor its objects to provide a segment carrier andsupporting and guiding means therefor, of simple, light, compact and inexpensive construction to provide improved antifriction supporting and guiding. means for the segment carrier; md to provide segment carrying and "guiding means which may be constructed of sheet metal, consists of a minimum number of parts, and may be readily assembled in a machine frame. Further objects of the invention-will appear from the description of i the improvements in connection with the accompanying drawings. r In the drawings, Fig. 1 is a frontelevation of the segment and the supporting and guiding means therefor, the segment and carrier being shown in the uppermost posi tion thereof;

Fig. 2 a view similar to Fig. 1, showing the segment and carrier in the lowermost position thereof; v

Fig. 3 a view similar to Fig. 1 with the segment removed; d

An integral angular carrier-guide 5 extends forwardly from the outer edge of eacHp'late I 4 a short distance, and is then bent inwardly I i at right angles'and widened" vertically at its inner end at 6. Each plate 4 of the guide members is provlded witha pair Of'anguQ larcarrier-guides or retainers 7 which ex tend forwardly from theinner edge'of the plate at points above and below the ad jacent guide 5 and are bent inwardly at right angles. The guides .5 are relatively wide vertically, while the guides 7 are com-.

paratively narrow vertically. The :inward 1y extending arms of the guides 7 are located in. a vertical plane at the rear of the plane of. the guides 5 and do. not extend inwardly toward thev longitudinal center of the machine frame as far as the. inwardly extending arms of guides 5. f

The segment carrier 8 comprises a flat sheet steel plate cut away intermediate itsends at its upper edge along a line corresponding substantially with the curvature of the type-bar segment 9., The segment '9 is detachably held to the carrier plate 8 by screws 10 extending vthrough apertures 11 in the plate 8, from'the rear face of said plate and threaded into lugs 12 formed'on the opposite ends of the segment. The vertical side edges of thecarrier plate 8 lie closely adjacent the innersides of the for wardly extending portions ofth'e angular guides. or retainers 7, and the front face of the plate .8 lies closely adjacent therear sides of the inwardly extending portions of said guides 7, thep late being, however, normally out. of contactwith said guides which "serve to prevent sidewise, forward or rocking movements ofthe platewhen the Any suitable keyoperated means may be I provided for moving the segment carrier 8 vertically relatively to the machine frame. to shift the segment 9 relatively to the platen and thus change the case. The carf1 rier is supported and guided immeve vertically with a minimum of :frictionfby a antifriction andsubstan'tially vshape in cross-.section'is secured to thefront face of the rear wall 1 of the machine frame by a pair of screws 14, I said. raceway member being located fmid- 11 at V supporting and guiding means. vertically. extending raceway member13 formed of sheet metal j" in a e mee pae lu ip y able edgewise eiiij'arli 211p lbWn direction in {the flame k to" chfa I ge I 'c ise, vel ticelly a spaced, polling elemept s located centrally aziclloc zjtted'it the other face dffthefeuppolr tf, v raceway members on the frame atthefeppe a, .111 A CiiSG gee fmchelli'sm; the icolribignation of ab subpoz t shi gffiehle edg wis el td be en ft a ry vary the relet ien means and a p laee r of rolling elefl gated" at orlle fe'ce Of the?hupporfifisubetang tially midway the Side elrlgesfefwth e"seppolib,

and antifriction rolling elements interposed between the three guide members and the support.
